Hemolytic activity and invasiveness in strains of Proteus penneri.
Twenty strains of Proteus penneri obtained from the Centers for Disease Control, Atlanta, Ga., were tested for their ability to hemolyze sheep and human erythrocytes, a property that is thought to be connected with the invasiveness and virulence of Proteus species. In the logarithmic phase of growth, P. penneri cultures are hemolytic for such erythrocytes. This ability is comparable to the hemo...
متن کاملSwarming growth and resistance of Proteus penneri and Proteus vulgaris strains to normal human serum.
BACKGROUND Proteus sp. strains isolated from patients with urinary tract infection (UTI) are often insensitive to the bactericidal action of normal human serum (NHS) which poses a clinical problem. The swarming phenomenon is an especially important factor in cases of UTIs gained through the ascending route. Both these virulence factors are connected with the cell surface components of bacteria,...
متن کاملProteus penneri and urinary calculi formation.
The clinical significance of Proteus penneri, a newly described species, is unknown. A case report is presented, which is to the best of our knowledge the first description of this organism causing a urinary tract infection and bladder calculi.
متن کاملExpanded clinical spectrum of infections caused by Proteus penneri.
Strains of Proteus penneri from seven abdominal wounds (after bowel resection), five urine samples, and eight other sites were isolated in mixed cultures. Seven urine isolates were in pure cultures. All infections were nosocomially acquired, indicating that complete identification of P. penneri in the clinical laboratory is warranted.
متن کاملCharacterization and serological classification of a collection of Proteus penneri clinical strains.
INTRODUCTION Bacteria of the genus Proteus, which are a common cause of urinary tract infections, are divided into four species: P. mirabilis, P. vulgaris, P. penneri, and P. hauseri, and three unnamed genomospecies, Proteus 4, 5, and 6 (single-strain species P. myxofaciens was isolated from the gypsy moth). Establishing the serological classification of these species would aid in completing th...
